    Approximately 192 gram of sodium nitrate

    Explanation:

    First we shall look at the solubility curves of NaNO3.

    Now, the solubility graph will allow you to find the solubility of the solute per 100 g of water at various temperatures.

    At 30∘C, Sodium Nitrate has a solubility of approximately 96 g per 100 g of water.

    We will use this value as a conversion factor to determine how much Sodium Nitrate can be dissolved in 200 g of water at 30∘C.

    200 gram of water * (96 gram of NaNO3 at 30 degree centigrade) / (100 gram of water) = 192 gram of NaNO3
